NEW YORK — Fashion week began, for me, with the Peter Pilottofor Target show at Gotham Hall. At the tail-end of the party — 9 p.m. — where models marched around a stage in the British label’s stock vivid cut-up prints and sharp tailoring — the place was still a mob scene.

Target has another big hit on its hands — maybe not of Missoni-for-Target magnitude, but close. Designed by Mr. Pilotto & Christopher De Vos, those clothes are going to sell out within days when they arrive in stores Sunday.

At the invitation-only pop-up shop on Thursday night, two men, shopping for girlfriends, haggled over who would get a $69 size 4 dress with a built-in petticoat. Women swarmed over the clothes, trying them on by the racks over their street clothes and helping each other with zippers. The whole shop was like Loehmann’s famous group dressing rooms. This morning, items were already selling on eBay for double the Target price.

It’s a great collection with everything from swim suits and sneakers to tailored jackets, all with the label’s eye-popping wake-me-up colors. Particularly amazing, for a label known for fabulous fabrics, is that Target managed to source cheaper materials that still have that electric Peter Pilotto vibe.

Peter Som stuck with the ’70s vibe that has fascinated fashion for some time. It seems like a good omen, because designers are doing the ’70s better now than they did back then. (Even polyester is so much better than back in the day.)

The strong points of his collection were the big-lapel trench coats, and blurry floral prints. But my absolute favorite look was a long-legged pantsuit with a belted double-breasted jacket, in a tweedy, ikat type fabric. The suit walked a fine line between louche and businesslike, and that’s tricky footwork.

It’s way too early in New York Fashion Week to start picking trends for the Fall 2014 collections, but I’m going to go out on a limb and make a couple anyway: metallic textiles and blurry prints. Write it down and hold me to it.
